In 2015 Oregon became the second state in the country to implement a statewide promise program. Its program, Oregon Promise, seeks to promote students' postsecondary attainment by covering nearly all community college tuition. This study used student data from K-12 public schools, Oregon Promise applications, and postsecondary records to examine which public high school seniors the program reached and served and to assess the program's impact on high school graduates' postsecondary outcomes in its first two years. The study found that Oregon Promise applicants generally reflected the demographic composition of all Oregon public high school seniors in 2015/16 and 2016/17, although applicants were more likely to be female and less likely to have received special education services. While applicant characteristics were similar in the first and second years, there were fewer eligible applicants and recipients in the second year, when an expected family contribution limit was added, than in the first year, and they were more likely to be from low-income households and to be students of color. Using grade point average (GPA) data from the Portland metropolitan area, the study also found that lowering the GPA requirement would have increased the overall applicant pool, as well as the number of applicants from low-income households and applicants of color. Just over half of recipients in the first year of the program renewed their award and received it in their second year at a community college. These recipients had better high school attendance and were more likely to have participated in college-level coursework during high school than recipients who received an award only in their first year. Finally, among high school graduates in the Portland metropolitan area with a GPA close to the eligibility cutoff (2.5), the offer of an award had a positive impact on first-year persistence and on persistence or college completion within four years of high school graduation. Findings from the statewide exploratory analysis also found positive program impacts on first-year persistence and persistence or college completion within three or four years of high school graduation for all 2015/16 and 2016/17 seniors in the state. Oregon stakeholders can use the findings to better understand the reach and impact of the Oregon Promise program, implications of program requirements on the number and composition of applicants and recipients, and the high school experiences of recipients who renewed their award.
